OMEGA Engineering offers pH electrodes with integral preamplifiers for laboratory or industrial applications.
These electrodes can interface directly with equipment that accepts a millivolt input signal with a 10 k½ or greater
input impedance, such as a data acquisition interface or multimeter. The preamplifier converts the high
impedance millivolt signal of the electrode into a low impedance signal, enabling the signal to be run up to
305 m (1000') without signal loss. The electrode is supplied with 1 to 3 m (3 to 10') of coaxial cable,
depending on the model. If longer cable lengths are required, simply splice on extension cable.

These preamplified electrodes are available in a variety of styles and can interface with any pH meter,
controller, transmitter, multimeter or data acquisition system with a
one-to-one unity gain.

The preamplified power option comes in styles: an encapsulated battery design, suffix "-PB", an
external battery style, suffix "-EB", and a style for use with an external dc power source, "-NB".To order a preamplified electrode see the To Order guide below.
